For the life of me I cannot find any instructions to connect the lilliput to draw power from the M2.

Can someone point me in the right direction please.

Seems this has caused at least half a dozen board failures already, most recently summarized here:

Very disappointed because of this...
Already bought (2) M2-ATX and apparently have damaged both of them due to this polarity issue on J9/J8 making that switch shorten and always powered. It's ridiculous since they don't properly mention this on the manual nor did they include +/- labels on the board, since when do you need to own a voltmeter to install a PSU???

On the 1st PSU the damage is clearly seen, on the 2nd I'm guessing its less obvious... Who is the manufacturer? I think this deserves out-of-warranty RMA.

Okay, i'm having a really hard time with the jumper settings. all the diagrams i see shows 4 rows a cross and 8 down but thats not what the board looks like. So can someone explain how to jump it so it is offdelay 5sec and hardoff 2 hours?

Just bridge the pins labelled with the letter B with a jumper.

anyone have issues with this with RFI?

Trying HD Radio and computer is causing a lot of RFI and destroys the FM signal. I'll be trying an AC PSU to see if there is a difference.
